🚀 Summary
This pull request adds the U-Mamba architecture to MONAI as proposed in Issue #7472. U-Mamba integrates the Mamba sequence modeling approach with the U-Net framework to enhance medical image segmentation performance.
📦 Changes Introduced
u_mamba.py: Implements the U-Mamba architecture under monai/networks/nets/
init.py: Registers the new model class for MONAI usage
test_networks_u_mamba.py: Adds a basic unit test for model instantiation and forward pass
🔧 Motivation
Adding U-Mamba expands MONAI's support for state-of-the-art architectures and enables research on efficient sequence modeling in medical imaging applications.
